Abstract

A method for welding a structure containing a gap which is exposed on either side of the gap is disclosed. The method is ideally suited for welding the gap which exists between the inner cylinder and nozzle chamber of a steam turbine during manufacture and repair. The method is accomplished by applying a refractory material into one side of the gap, preferably with the aid of gravity while the structure is inverted. When the refractory material is in place, the gap is welded. Upon completion of the welding procedure, the refractory material is preferably removed. In accordance with the present invention, a substantially uniform weld can be made upon a gap which is exposed on either side without the need for a controlled precision initial root weld.
